Abstract

The present invention provides compositions comprising a) at least one polymer consisting of one polymerblock A and at least two polymerblocks B, wherein each polymerblock B is attached to the polymerblock A, and wherein at least 60 mol % of the monomer units of polymerblock B are selected from the group consisting of Formulae (1A), (1B), (1C), (1D), (1E), (1F) and 1G, 1H and 1I wherein R1, R2, R3, R4, R5, R6, R7 and R8 are independently and at each occurrence H or C1-10-alkyl, and b) at least one crosslinking agent carrying at least two azide groups, as well as to layers formed from these compositions, electronic devices comprising these layers and to specific polymers encompassed by the polymers of the composition.
